Brief introduction of functions:
3062322(speed controller) is a design with full electrical closed-loop path control function, which cancontrol Cummins engine perfectly when connecting with the matched actuator in EFC system, as it cancontrol the engine speed rapidly and accurately once getting instantaneous loading change.2, Specification:a, Electric Specification:RPM Stability: <0.25%Speed Range: 1KHz ~ 6.5KHzThermal stability: Max 0.7%IDLE Regulation: 260 20HzDROOP Regulation: Minimum 15Hz 6Hz/ 1 Amp; Maximum: 400Hz 75Hz/ 1 AmpExternal Speed Regulation: 200Hz (with 1 K connected)AUX Input Sensitivity: 148Hz / 1V., 10HzImpedance: 1Mb, ENVIRONMENT:Working Temp Range: -40 ~ 85Working Humidity Range: Maximum 95%Stocking Temp: -55 ~ 92Shocking: 20-100HZ 500mm/Sec.c, INPUT POWER SUPPLYVoltage: 12V or 24VGrounding Pole: Negative polePower Supply: 40mAActuator Continuous Current: Minimum 1A, Maximum 4.5AMPU Signal: 2 ~ 120V RMSNOTE: Above-Mentioned parameters are tested with a 3800Hz working frequency.3, Installationplease use antiskid self-lock screw to install after making hold in the suitable places according to thefollowing data.the distance between the center and four hole is 135mm*102mm, the diameter of the hole is 5.5mm.Terminals’ introduction is as below:Speed controllerNo.1,No.2 terminals: 1 is DC positive, 2 is DC negtive.No.3,No.4 terminals are the output connector of ACTUATORNo.5,No.6 terminals are the input connections of MPUNo.7,No.8,No.9 terminals are external RPM fine tuningNo.10 is the connector of idle-speed switchNo.11 terminal is free connector4, adjustmentThe speed controllers shall be adjusted before sending out from factory, but it can be adjustedslightly again during the operating according to different engine models, the operation is as below:a, adjust to the initial position:if wrong operation is made during the operation that the potentiometers adjustment is in a messthen please adjust as the instruction below:stop engine and switch off the power of speed controller:please adjust IDLE SPEED to middle point(turning around 20 circles. Firstly use inverteddirection to the bottom then turn around 10 circles in clockwise direction)please adjust RUN SPEED to middle point (turning around 20 circles,Firstly use inverteddirection to the bottom then turn around 10 circles in clockwise direction )please adjust GAIN to 20%~50%(turning around 1 circle)please adjust DROOP TO 0b, IDLEUsually the IDLE speed is 600-800 RMP per min, if turning IDLE in clockwise direction,theRPM will be increased;if turning IDLE in inverted direction, the RPM will be decreased.c, RUNUsually the speed of idle load is 1515RPM per min(50.5Hz), rated load is 1500RPM permin(50.0Hz). if turning RUN in clockwise direction,the RPM will be increased;if turning RUN ininverted direction, the RPM will be decreased.d, GAINThe running speed of engine responses rapidly when turning GAIN in clockwise direction,the running speed of engine is stable when turning GAIN in inverted direction, the places are inNo.5-No.7.on the occasion of idle load, please adjust GAIN in clockwise direction slightly till therunning speed is up, then ajust GAIN in inverted direction slightly till the speed is stable.e, DROOPThe function of DROOP: when the load is increased, then running speed of engine will bedecreased. if turning DROOP in clockwise direction, then the running speed’s drop-out value will beincreased; if turning DROOP in inverted direction, then the running speed’s drop-out value will bedecreased.
